For example, microphones 108 may be placed at optimal locations along contour edges 110, where optimal locations are locations which maximize available audio data from users and/or minimize noise, such as propagating vibrations.

(18) Contour edges 110 may include a chamfer, where a chamfer is a symmetrical sloping surface at an edge or corner. An angle between a top surface of table top 102 and a sloping surface of a chamfer of contour edges 110 may be between 0 and 90 degrees, exclusive, or between 90 and 180 degrees, exclusive.

(19) Microphones 108 may include a capacitor microphone. A capacitor microphone may have multiple capacitive plates. A diaphragm may act as one of the plates so that vibrations produce changes in a distance between the plates. As the distance between the plates changes, so does a capacitance between the plates.
